Lubricating Oil Consumption, Centrifuges and List of Lubricating Oils
Lubricating oil consumption
The system oil consumption varies for different
engine sizes and operational patterns. Typical
consumptions are in the range from
negligible to 0.1 g/kWh
subject to load, maintenance condition and in-
stalled equipment like PTO.
Lubricating oil centrifuges
Automatic centrifuges are to be used, either with
total discharge or partial discharge.
The nominal capacity of the centrifuge is to be
according to the supplier’s recommendation for
lubricating oil, based on the figure:
0.136 litre/kWh
The Nominal MCR is used as the total installed
power.

List of lubricating oils
The circulating oil (lubricating and cooling oil)
must be of the rust and oxidation inhibited type of
oil of SAE 30 viscosity grade.
In short, MAN Diesel and Turbo recommends the
use of system oils with the following main proper-
ties:
• SAE 30 viscosity grade
• BN level 5-10
• adequately corrosion and oxidation inhibited
• adequate detergengy and dispersancy.
The adequate dispersion and detergent proper-
ties are in order to keep the crankcase and piston
cooling spaces clean of deposits.
Alkaline circulating oils are generally superior in
this respect.
The major international system oil brands listed
below have been tested in service with acceptable
results. Some of the oils have also given satisfac-
tory service results during long-term operation on
MAN B&W engines running on heavy fuel oil (HFO).
Oils from other companies can be equally suitable.
Further information can be obtained from the en-
gine builder or MAN Diesel & Turbo, Copenhagen.
